AGP modes and what they mean?

I've been looking at the settings on my new graphics card and wondering what AGP does. I have not touched anything as I'm very well satisfied with the graphics so far. However, the agp is set 2x instead of 8x? Should I boost it to 8 and why?

Those settings have to do with increased speeds through the AGP bus which of course is how your video card is connected to your motherboard and thus your CPU and monitor. What is your motherboard capable of? i would think that your vc and mobo should match but i do not know what happens if they are not matched.

the motherboard I think is capable of 4x so I will set it to that. Thanks Madrus.

yes it depends... AGP 8x is new and video processors and memory can not yet move data that fast. even though a video card is 8x does not mean the rest of it can push data that fast. agp stands for accelerated graphics port, and was created from the PCI standard to streamline the data flow between video cards and memory/cpu.

it is the speed of the AGP bus, which is attached to your memory and cpu through your motherboard (as stated above). The number (i.e. 8x) is the bus speed relative to the opriginal agp 1x bus speed (recommedation - it was only a recommendation and may still did it at 33 MHz) of 66 MHz. So 8x agp is 533 MHz.

now part of the spec says that all cards must be backwards compatible since agp 2x. so if you have an 8x card it will work in a 4x motherboard. generally this is all done automatically. maybe your motherboard is different, but the agp spec is designed for the motherboard to detect the speed of the card and run it as fast as possible. also make sure our card is capable of running as fast as you are going to "set" it...

also, your 4800 had better be an 8x card...!!! check with SB on what speed the agp port is capable of on that board.

The Max AGP speed on the KR7A RAID board is 4x. The 8x speed is pretty new and only a few motherboards out there support it. The 4800 card is esentially a 4600 card, but the "8" in 4800 stands for 8x, and so the card is a 4800. So, bottom line, that card is ready for your next MB upgrade. Well, one that supports 8x AGP. :) Let me know how you like that MSI 4800 card, I have a friend that is thinking about getting one.

Grif, how you like your new rig so far? Much faster than the 500Mhz eh? :D

This thing flies! It's simply awesome. I'm having a little trouble with the graphics card,but I think it's just my monitor's refresh rate or something.
